“On a day-to-day basis there are difficulties but that is the same in any relationship. I can be sensitive so I guess that makes it more challenging.”

Packham has been open about his struggles with Asperger’s and revealed if a cure was available he is unsure whether he would take it.

In an interview with the Radio Times, he said: “If there were a cure for Asperger’s, I don’t know if I’d want it.

“Humanity has prospered because of people with autistic traits. Without them, we wouldn’t have put man on the moon or be running software programs.
